A New Book

I have tried reading this but I just can't concentrate on it. Yesterday I think I read the same paragraph several times.
When I bought it I didn't realise it was going to be on the tv. I'll read the book first then watch it.

I crawled to work this morning , ditching the walking option and taking the car. I had a little snooze at lunch then a big coffee. It got me through.

Home and I collapsed, physically and mentally. I tiredness kicked in and I sat on the sofa and cried for no reason. Got annoyed with myself and felt panicky, hot and then self harmed.

What is wrong with me?
